Mammalian Pheromones
Topic 6: Mammalian Pheromones
Abstract
A pheromone is a chemical signal which is released by one animal and received by another, which induce a species specific reaction. Pheromones are detected via chemosensory systems known as the Vomeronasal Organ (VNO). Within a wide range of mammals the VNO is used to elicit a generalized sexual response, primarily affecting the reproductive tract. This is seen in most terrestrial mammals who have adapted to sensing volatile chemical signals; the Mouse displays the general VNO function. Additionally, some mammalian species have adapted the ability to respond to a variety of pheromonal signals which can alter their physiological behavior. Mice can also respond to chemo-signals from animals within and
